If your local villagers neglected to unearth and stake a suspected vampire and he or she has returned from the grave, there are steps you can take to protect yourself. The exact method varies around the world, but in some traditions the best way to stop a vampire is to carry a small bag of salt with you. If you are being chased, you need only to spill the salt on the ground behind you, at which point the vampire is obligated to stop and count each and every grain before continuing the pursuit. If you don’t have salt handy, some say that any small granules will do, including birdseed or sand. Salt was often placed above and around doorways for the same reason.
Some traditions hold that vampires cannot enter a home unless formally invited in. This may have been an early form of the modern “stranger danger” warnings to children, a scary reminder against inviting unknown people into the house.
